LEVER ADJUSTMENT.

Original application filed May 28, 1919, Serial No. 300,365.

Divided and this application filed Gcto'ner 17, 1919.

To aZZ whom it may concern:

Be it known that 1, VI ALTER J. BURCHETT, citizen of the United States, residing at Last Orange, county of Essex, State of New ful lniprovements in Lever Adjustments, of

which the following is a specification.

N y invention relates to means for adjustably attaching the operating arm or lever of a power mechanism to a shaft for the purpose of imparting oscillatory or other movement to said shaft, and is a division of an application filed by me May 28, 1919, Serial No. 300,365.

The main object of this invention is to provide a simple and eilicient means for adjusting said arm with respect to said shaft, so that the device is adapted for use with various forms of machinery and in any desired position.

In the accompanying drawing:-

Figure 1 is a .e elevation partly broken away of my improved arm applied to a shaft to be operated.

Figure 2 is a horizontal sectional view of the same, taken on the line II-Jl of Figure 1.

Similar numerals of reference denote corresponding parts in the two views.

In the said drawing, the reference numeral 1 denotes the operating arm or lever having adjustably mounted its outer end a suitable fastening i evice 2, whereby it is adapted to be connected to some operating part of the machine by which it is operated. The shaft 3 to be operated by said lever is reouced near its upper end at said reduced portion being provided with a flattened side 5 removably to receive a. star wheel 6, said star wheel being apertured to conform to the contour of the portion t of said'shaft. as best seen in Figure 2. The upper end of the shaft 3 is still further re duced at T and is sci w-threaned at its upper end. said reduced portion '7 receiving the inner end of the lever l, the latter when in position resting upon the star wheel 6. Disposed above the lever l on the reduced portion T is a washer 8, all of these parts being retained in position by a nut 9 engaging the Specification of Letters Patent ersey, have invented certain new and use-' Patented Mar. 21, 1922.

Patent No. 1,339,844, dated May 1i, 1920.

Serial No. 331,455.

screw-threaded upper end of the reduced portion 7. Riveted or otherwise fixed to the lever l is a lug 10, adapted, when the lever is in position on the shaft 3, to engage between any two of the teeth of the star wheel 6, as shown in Figure 2, thereby locking said lever and star wheel in such position.

The device when adjusted to the position shown in the drawing is particularly well adapted for transmitting a vibratory motion imparted to the lever 1 from any suitable machine to the shaft 3, but frequently it is found desirable that the position of the lever 1 with respect to the shaft 3 be shifted in order to suit different forms of'machines from which operation is imparted. This readily can be accomplished by loosening the nut 9 sufficiently to permit the lever l to be raised far enough to disengage the lug 10 from the teeth of the star wheel 6. Said lever then may be moved radially so that the lug 10 will engage between any other two of the teeth of the star wheel 6, and upon being dropped to position therebetween again may be clamped by resetting the nut 9.

in my application for Letters Patent No. 300,365, I have shown this device applied to a counting mechanism, for which it is particularly well adapted. But it will be understood that it is not limited to any such use, as it may be applied to any character of device wherein an adjustment of the lever i ith respect to the shaftB may be desired.

Having thus described my invention, what i claim as new and desire to secure by Letters Patent, is

in a device of the character described, a V
